You can assign other protocols to unused channels the if data rate and clock specification exactly match

the PCIe configuration.

PIPE Interface Signals

These PIPE signals are available for Gen1 and Gen2 variants so that you can simulate using either the

serial or the PIPE interface. Simulation is much faster using the PIPE interface because the PIPE

simulation bypasses the SERDES model . By default, the PIPE interface is 8 bits for Gen1 and Gen2. You

can use the PIPE interface for simulation even though your actual design includes a serial interface to the

internal transceivers. However, it is not possible to use the Hard IP PIPE interface in hardware, including

probing these signals using SignalTap
